Abstract
Proteklih godina povećan je interes za razgradnjom lignocelulozne biomase zahvaljujući njezinoj ulozi kao supstrata u proizvodnji biogoriva i različitih bioprodukata. Osim poljoprivrede i prehrambene industrije, velika količina lignoceluloznog otpada zaostaje i u drvnoj industriji. Osnovne sastojke drvne biomase čine celuloza, hemiceluloza i lignin. Najveći izazov za potpuno ostvarenje potencijala lignoceluloznih materijala kao supstrata za proizvodnju vrijedninh biotehnoloških produkata je svladati njihovu veliku otpornost prema razgradnji do fermentabilnih šećera. Skupina filamentoznih gljiva koje razgrađuju drvo (gljive truležnice) imaju sposobnost razgradnje lignoceluloznih sastavnica drva do različitih spojeva. Gljive truležnice mogu se podijeliti na gljive mekog truljenja, gljive smeđeg truljenja i gljive bijelog truljenja. Gljive bijelog truljenja u koje se ubrajaju i C. subvermispora, T. versicolor i P. chrysosporium imaju sposobnost razgradnje sve tri gore navedne sastavnice drva. Enzimi koji sudjeluju u razgradnji lignina pomoću gljiva pripadaju skupini ekstracelularnih peroksidaza: lignin peroksidaza, mangan peroksidaza i lakaza.

Parallel abstract (English)
In recent years, there has been an increasing interest in degradation of lignocellulosic due to their use as substrates for biofuels and different bioproducts production. Apart from agro-food industry, wood industry is also a generator of large amounts of lignocellulosic residues. Wood biomass consists primarily of cellulose, hemicelluloses and lignin. A major challenge to full realization of the potential of lignocellulosic biomass is to overcome their high degradation resistance to become fermentable sugars. Filamentous wood-rotting fungi are able to degrade lignocellulosic components to various extents. They are generally grouped into softrot, brown-rot and white-rot fungi. White-rot basidiomycete fungi that comprises also C. subvermispora, T. versicolor and P.chrysosporium are capable of degrading and mineralizing all three above mentioned polymers. Enzymes involved in fungal lignin degradation are extracellular peroxidases: lignin peroxidases, manganese peroxidases and laccase.
